Web-based Games Development

We need a developer to work on an existing web project to do code bug fixes, improvements and updates. New games might be added in the future. The games are built using ReactJs for the frontend while the backend uses C# .NET. Payments will be milestone-based (e.g. for every feature request, there will be a budget allocated to it).

Note that this is an ongoing project and developer could be hired as monthly employee (remote).
